Analytical Reagents 4-Dimethylaminobenzaldehyde For Pressure And Heat Sensitive Dyes

Analytical reagents Cosmetic Intermediates 4-Dimethylaminobenzaldehyde CAS 100-10-7 Pressure and heat sensitive dyes

Introduction:

p-Dimethylaminobenzaldehyde is an organic intermediate that can be prepared from N,N-dimethylaniline and DMF. Literature reports that p-Dimethylaminobenzaldehyde can be used to prepare high-purity DAST source powder, and can also be used to make colorimetric solutions to analyze aminohydroxyurea. White or light yellow leaf-like crystals or powder. Melting point 74°C, boiling point 176-177°C (2.27kPa), flash point 164°C. Soluble in alcohol, chloroform and acetic acid, slightly soluble in water. Has a benzaldehyde-like odor and gradually turns red when exposed to light.

Uses:

p-Dimethylaminobenzaldehyde can be used as a dye intermediate and analytical reagent. It is used to determine indole, skatole, urea blue, tryptophan and ergot alkaloids, and is also used to distinguish serum eruptions from scarlet fever. In terms of dyes, it can be used to synthesize pressure-sensitive dyes. It is also used to produce cationic brilliant red G (C.I. Basic Red 52). Also known as Euler's solution/E reagent, it is mainly used for the identification of enterobacteriaceae, non-fermenting bacteria, fastidious bacteria, anaerobic bacteria, and the detection of indole derivatives and amines.
